Designed for socket mounting with quick-connect terminals, this component features a DPDT (2 PDT) contact configuration utilizing silver nickel (AgNi) contact material. It operates with a nominal coil voltage of 24 V DC, drawing a typical input current of 41 mA, and incorporates an integrated freewheeling damping diode, a yellow status LED, a test key, and a mechanical switch position indicator for streamlined diagnostics and maintenance. Electrical parameters include a maximum switching voltage of 250 V AC/DC and a limiting continuous current rating of 12 A. The relay supports a maximum inrush current of up to 30 A for 20 ms on normally open contacts and provides a maximum ohmic interrupting rating of 288 W at 24 V DC or 3000 VA at 250 V AC. Operating within a temperature range of -40 °C to 70 °C, the unit features a dielectric test voltage rating of 2.5 kVrms between the coil winding and contacts, satisfying IEC 61810 standards for surge voltage category III and pollution degree 3. Measuring 21.2 mm in width, 35.6 mm in height, and 27.5 mm in depth, this industrial relay delivers an estimated mechanical service life of 2 x 10^7 cycles. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (04-Feb-2026) | | Coil Type | - | | Coil Voltage | 24VDC | | Product Range | REL-IR2/LDP Series | | Relay Mounting | Socket | | Coil Resistance | - | | Contact Current | 12A | | Relay Terminals | Quick Connect | | Contact Material | Silver Nickel | | Contact Voltage Vac | 250V | | Contact Voltage Vdc | 250V | | Contact Configuration | DPDT | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3256156/) ## **Extract from the online catalog** ## **REL-IR2/LDP- 24DC/2X21** Order No.: 2903660 ## http://catalog.phoenixcontact.net/phoenix/treeViewClick.do?UID=2903660 Plug-in industrial relay with power contacts, 2 PDTs, test key, status LED, freewheeling diode, mechanical switch position indicator, polarity: A1+, A2-, input voltage: 24 V DC ## Product notes WEEE/RoHS-compliant since: 07/03/2012 |**Commercial data**||||||||||||||||||||||||07/03/2012| |---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| |||||||||||||||||||||||||| |EAN|4
